An electricity charging system includes: a charger portion that charges a storage battery; a detection portion that detects an amount of charge stored in the storage battery; and a control portion that controls electric power that is supplied to charge the storage battery by the charger portion so that the electric power changes by a predetermined rule, according to the amount of stored electricity detected by the detection portion.

Electricity charging system

An electric power supply system includes a connecting device that connects a secondary battery provided in a vehicle to a building, and a control apparatus that i) identifies the type of the vehicle that is connected to the connecting device, the type of the secondary battery, or the type of electric power that is distinguishable by the charging source of the electric power stored in the secondary battery, ii) determines a preset electric power supply method based on the identification results, and iii) controls a supply of electric power from the secondary battery to the building based on the determined electric power supply method.

Electric power supply system and electric power supply method

An energy management system has an integration control portion that performs control to charge a storage battery with a power of such an amount that a power consumption including a power supplied by a supply portion is equal to or smaller than a target value indicated by power consumption target information recorded in a recording portion when a power consumption detected by a detection portion is smaller than the target value, and to supply a building with a power with which the storage battery is charged such that the power consumption including the power supplied by the supply portion coincides in amount with a power equal to or smaller than the target value indicated by the power consumption target information recorded in the recording portion when the power consumption detected by the detection portion is larger than the target value.

Energy management system

A user inputs a travel distance after last charging of a storage battery of a vehicle into an input field. A capacity of the storage battery at a current charge starting point in time is estimated from a capacity of the storage battery at a last charge ending point in time stored at the last charging and the input travel distance. The estimated capacity of the storage battery is displayed in a display field. During charging of the storage battery, detecting charge current and voltage to estimate a current capacity of the storage battery during charging, a remaining charging period of time and a distance-to-empty by the current capacity and displaying the estimated current capacity, remaining charging period of time and distance-to-empty in display fields are repeated.

Charging device and charging method that notify a user about the state of charge of a vehicle storage battery

A charging start time and preliminary air conditioning time are calculated based on the departure time that is set with a control/operation device (S), and the charging time and preliminary air conditioning time are set (S). Then, a control is executed to start charging when at the charging start time (Sto) and preliminary air conditioning may be started when the amount of charge is sufficient for preliminary air conditioning and a preliminary air conditioning starting trigger is detected, that is locking or preparation for leaving house is detected, for example (Sto).
